Bill Wasik is credited with introducing the notion of a flash mob in 2003, said in 2010 that he was surprised by the violence of some of the gatherings. He said the mobs started as a kind of playful social experiment meant to encourage spontaneity and big gatherings to temporarily take over commercial and public areas simply to show that they could. “It’s terrible that these Philly mobs have turned violent,” he said [1].
